The six independent formfactors describing the weak decay Λb → Λceνe are determined in terms of one universal function when both the b and c quarks are treated as heavy. The relations between these formfactors are modified by terms suppressed by inverse powers of the charm quark mass. We compute the formally leading long-distance corrections to these relations in chiral perturbation theory both...

For a convex body C in a Euclidean vector space X of dimension n (≥ 2), we define two sub-arithmetic monotonic sequences {σC,k}k≥1 and {σo C,k}k≥1 of functions on the interior of C. The k-th members are “mean Minkowski measures in dimension k” which are pointwise dual: σo C,k(O) = σCO,k(O), where O ∈ int C, and CO is the dual (polar) of C with respect to O. They are measures of (anti-)symmetry ...

Most elliptical galaxies contain central black holes, whose masses scale proportionally to the observed central velocity dispersions of the host galaxies according to the so–called MBH − σc relation. Here we discuss some consequences that can be derived by combining the MBH − σc relation with the scaling relation describing the Fundamental Plane of elliptical galaxies. In particular, the possib...

The focus of this paper was directed towards investigating the influence multiple freeze–thaw (FT) cycles on mechanical behaviors an expansive soil under a wide range confining stresses (σc) from 0 to 300 kPa. Consolidated undrained (CU) shear tests with pore pressure measurement (σc = 10–300 kPa) and unconfined compression (UC) were conducted FT impact specimens derive shearing stress–strain r...

A many-body theory of molecular junction transport based on nonequilibrium Green’s functions is developed, which treats coherent quantum effects and Coulomb interactions on an equal footing. The central quantity of the many-body theory is the Coulomb self-energy matrix ΣC of the junction. ΣC is evaluated exactly in the sequential tunneling limit, and the correction due to finite tunneling width...

Spitzer 70μm confusion measurements are presented based on ultra-deep MIPS-70μm observations of GOODS Hubble Deep Field North (HDFN). The instrument noise for the MIPS-70μm band integrates down with nearly t for the low background HDF-N field. The estimated confusion level is σc = 0.30± 0.15mJy for a limiting flux density of 1.5mJy (q = 5).

Abstract Since rock is heterogeneous, hence its behavior always variable. The governing parameters in deformations are time, applied load, composition, water content, temperature and loading conditions including confinement rate. Time-dependent deformation study extremely important for the prevention of hazards such as rockburst, roof fall collapse. In current study, sandstone samples from Kouz...
